The documentary study analyzed 50 documents, comprising 23 research articles, academic papers, theses, independent studies, and other publications on live-stream marketing communication, along with 27 documents outlining guidelines for developing live-streaming skills. These documents were sourced from Thai Journal Online (ThaiJO) and Google Search Engine between 2014 and 2024. The research instruments included a data screening form and an evaluation form to assess the appropriateness of guidelines for developing live-stream skills on e-commerce platforms for entrepreneurs in the digital era. Statistics used were frequency, percentage, mean, standard deviation, and content analysis.</p> <p>The research findings identified 1) six major aspects and 20 minor aspects influencing live-stream marketing communication, along with four major aspects and 29 sub-guidelines for developing live-streaming skills on e-commerce platforms. 2) The overall appropriateness of the proposed guidelines was at the highest level. The highest average score was effective marketing strategies, followed by systematic and concrete evaluation of live-stream performance for improvement and development of live-stream communication skills and effective content presentation, respectively. The lowest average score was selection of appropriate platforms and timing for live-stream marketing communication. Experts recommended incorporating a learning model that emphasizes experiential learning and an effective marketing strategy focusing on forming the right partnerships to facilitate knowledge exchange in high quality live-streaming.</p> Nampetch Nithiubut Patchara Eamcharoen Copyright (c) 2025 Institute of Vocational Education Southern Region 1 Journal https://creativecommons.org/licenses/by-nc-nd/4.0 2025-10-25 2025-10-25 11 1 13 23 https://ph01.tci-thaijo.org/index.php/csnp_veis1/article/view/261492 <p>The purposes of this research were to: 1) compare students' problem-solving abilities before and after receiving STEM education concepts, 2) compare students' problem-solving abilities learning with STEM concepts according to 75 percent criteria, 3) compare students' scientific creativity before and after with STEM concepts, and 4) compare students' scientific creativity after learning with STEM concepts according to 75 percent criteria. The research was a quasi-experimental study on one-group pretest-posttest design. The population of this research included 213 students of year 1 to year 3 in vocational certificate level of Samut Prakan Technical College in Samut Prakan Province from 9 classrooms in semester 2, the academic year 2024. The sample comprised 33 first-year vocational certificate students from Construction Engineering Department, selected through cluster random sampling. The research instruments included: 1) 3 lesson plans based on STEM with 6 hours per lesson, totaling 18 hours, 2) a problem-solving ability test, and 3) a scientific creative thinking test. Research statistics included percentage, mean, S.D., and t-test.</p> <p>The results of the research revealed that 1) the students' problem-solving ability after learning with STEM was higher than that before at the .05 level of statistical significance. 2) The students' problem-solving ability after receiving STEM concept was higher than the 75 percent criterion at the .05 level of statistical significance. 3) The students' scientific creativity after receiving STEM education concepts was higher than that before at the .05 level of statistical significance. Finally, 4) the scientific creativity of students after receiving STEM education concepts was higher than the 75 percent criterion at the .05 level of statistical significance.</p> Pornmanee Huikia Tweesak Chindanurak Duongdearn Suwanjinda Copyright (c) 2025 Institute of Vocational Education Southern Region 1 Journal https://creativecommons.org/licenses/by-nc-nd/4.0 2025-10-25 2025-10-25 11 1 24 33 https://ph01.tci-thaijo.org/index.php/csnp_veis1/article/view/261894 <p>The purposes of this research were to: 1) examine the creative leadership of the school administrators under the Office of the Vocational Education Commission in Nakhon Si Thammarat Province, 2) investigate the academic management of the educational institutions, 3) study the relationship between creative leadership and academic management, and 4) identify predictive variables of creative leadership that influence academic management. The sample consisted of 260 teachers selected through stratified random sampling based on the size of the educational institution.

This study employed a research and development (R&amp;D) design, consisting of three phases. Phase 1: Needs Assessment –questionnaires were used to collect data from 59 participants consisting of school administrators and teachers. Phase 2: Guideline Development – the instrument was a focus group discussion protocol of 9 experts. Phase 3: Guideline Evaluation – the instrument was an assessment form to evaluate appropriateness and feasibility of the guidelines validated by 5 specialists. The data were analyzed by research statistics including mean, standard deviation, content analysis, and the modified priority needs index (PNI_modified).</p> <p>The research findings were as follows. 1) Needs Assessment: the highest priority need in the input factor was the development of effective operational innovations (PNI_modified = 0.27). For the process factor, the priority was on using operational results to improve and develop further actions (PNI_modified = 0.21). For the output factor, the need was for appropriate student grouping <em>(</em>PNI_modified = 0.16<em>)</em>. 2) Development of the guidelines and input: the emphasis was placed on systematic innovation development. Process: school administrators should participate in every teacher PLC (Professional Learning Community) meeting. Output: homeroom teachers should study the screening criteria and group students accordingly. 3) Evaluation of the guidelines: the developed guidelines were rated as highly appropriate and feasible by the experts.</p> Kolanya Chukaew Pichamon Sureeyaphan Anu Jarernvongrayab Copyright (c) 2025 Institute of Vocational Education Southern Region 1 Journal https://creativecommons.org/licenses/by-nc-nd/4.0 2025-10-25 2025-10-25 11 1 66 75 https://ph01.tci-thaijo.org/index.php/csnp_veis1/article/view/261913 <p>The research aimed to: 1) investigate the level of ethical leadership among school administrators under the jurisdiction of local administrative organizations in Krabi Province, 2) examine the level of operation of the student care and support system in schools under the jurisdiction of local administrative organizations in Krabi Province, 3) study the relationship between ethical leadership and the operation of the student care and support system in these schools, and 4) identify the ethical leadership variables that can predict the operation of the student care and support system of these schools.
